EBC’s USR slotted front rotor set is a UK-made, precision-machined vented rotor specified at 280mm diameter, 26mm thickness and 47.5mm height with four bolt holes for the listed FMSI pad D924. The slotted USR design uses narrow slots to reduce air noise, help brakes run cooler and limit fade at speed, preserving pad flatness—advantages realized when paired with an appropriate high-friction pad.
